TranSpec-DSP Spectrometer
general hardware description

Powerful 16-Bits Analog-Digital Electronics

For the scanning of the photodiode array and the A/D-conversion of the spectrum, the TranSpec-DSP spectrometers use a fast and highly linear 16 bits A/D-converter. Due to the extremely short scanning time of the photodiode array (256 microseconds for an array of 256 diodes), the TranSpec-DSP instruments can be described as real simultaneous spectrometers. The high linearity of the A/D-converter permits reliable, reproducible photometric measurements over the entire useable signal dynamic range. TranSpec's effectively useable dynamic range of 16 bits has been achieved by the careful selection of high-quality electronic components.

Integrated DSP-Computer Electronics

The spectrometer systems are equipped with a high performance computer system based on Digital Signal Processors (DSP), so that the instrument can utilize the very short scanning time for a continuous and loss-free spectra scanning. Due to this integrated computer system, the spectra scanning and data preparation is performed independently by the TranSpec-DSP spectrometers, i.e. without any participation of an external connected PC. This ensures a constantly high measuring rate, which is independent of the performance of front-end computer system. Furthermore, TranSpec-DSP spectrometers have a generously dimensioned spectra memory (up to 14,400 spectra for a photodiode array of 256 diodes), which serves as an intermediate memory for the continuous and loss-free spectra scanning.
